- IMPROVEMENT IN PLOWS.

Specication forming part of Letters Patent No. 219,687, dated September 16, 1879; application led March 13, 1879.

To all 'whom it may concern:

Be it known that I, MANLovE BUTLER, of Vernon, in the county of Jennings and State of Indiana,vhave invented certain new and use- .ful Improvementsin Flows; and I do hereby declare that the followingy is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and* to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view of aplow representing my invention. Fig. 2 is a vertical section of the same. Fig. 3 is a bottom View of same with the point removed. Fig. 4 is a perspective view of the point. Fig. 5 is a perspective view of the key. l

,Identical parts' in the drawings are designated and referred to bythe sanne letters.

My inventionrelates' to plows; and it consists in. a frog in the bottom of the plow, at the point, extending from the land-side4 to the mold-board side, to which is attached a flat.

point provided witha cutting point or projec- `tion extending under the land upon the landside, and the point made adjustable by means of a stud, slots, a bolt, and key, as will hereinafter more fully appear.

A is the standard ofthe plow. B is the mold-board, constructed and attached in the usual manner. Gis the frog, located in fthe? bottom of the plow and at the point, connecting with the mold-board at c, and provided with a flange, c1, to which the land-side D is attached by the bolts d, which flange is also attached to the standard of the plow by the bolts a. In this frog C there are two slots, c2 c3. The bolt E passes throughthe aperture e in the point F and the slot c3 in the frog and the slot g in the key G. The slot c2 is for the introduction of the hooked stud f. j

The point F is provided with a common elongated point, F', and a point, F2, the latter extending horizontally upon the land-side of the plow for cutting under the land in such a manner as to render the turning of the following furrow easier, and by means of which a plow can be made to turn a wider furrow than without this point F2.

The key G is placed upon the upper side of the frog C, with its incline g engaging the hook of the stud f, while the bolt E retains it in its position. The slots c2 and c3 of the frog C and the slot g of the key G enable the point F to be adjusted and projected in case of wear.

I am aware that heretofore there have been projecting points on a plow similar to the point F2. F2 broadly; but y What I do claim as new, and which I desire to secure by Letters Patent isf The point F, provided with the hole e, stud f, and points F1 and F2, in combination with the frog C and key G, constructed and operating as described, as and for the purposes substantially as set forth. y

In testimony that I claim the foregoing as 4my own I aflix my signature in presence of two witnesses.

MANLOVE BUTLER.
